- Improves op performance. - Handle op-metadata (errors, promise IDs) explicitly in the op-layer vs per op-encoding (aka: out-of-payload). - Remove shared queue & custom "asyncHandlers", all async values are returned in batches via js_recv_cb. - The op-layer should be thought of as simple function calls with little indirection or translation besides the conceptually straightforward serde_v8 bijections. - Preserve concepts of json/bin/min as semantic groups of their inputs/outputs instead of their op-encoding strategy, preserving these groups will also facilitate partial transitions over to v8 Fast API for the "min" and "bin" groups

// This file defines the public interface for dynamically loaded plugins.
|
|
|
|
// The plugin needs to do all interaction with the CLI crate through trait
|
|
// objects and function pointers. This ensures that no concrete internal methods
|
|
// (such as register_op and the closures created by it) can end up in the plugin
|
|
// shared library itself, which would cause segfaults when the plugin is
|
|
// unloaded and all functions in the plugin library are unmapped from memory.
